Caring for oneself is a necessary part of caring for others, according to Joe Sparks, the former triathlete who helms Hot Yoga With Joe. To encourage others to devote more time to their health and loved ones, he and his staff of certified instructors fill fitness classes with both fun and restorative relaxation. Joe channels more than 10 years of teaching experience to lead hot-yoga workouts featuring gentle yet powerful poses that aim to forge cast-iron muscles capable of hurling a paper airplane into orbit. The 95- to 100-degree temperatures unspool tight ligaments and encourage sweat glands to flush toxins out of the nearest pore. New students prepare for their first sessions by completing a mandatory waiver and hydrating themselves thoroughly beforehand.
